Application filed April 29, 1913. Serial No. 764,411.

To ail whom it may concern Be it known that I, CARI.- ALoYs GRfiNE- WALD, a subject of the German Emperor, and residing at 38 Schneiderberg, Hanover, Germany, have invented certain new and useful Improvements in Filing Apparatus, of which the following is a specification.

This invention relates to filing cabinets and the-like.

The object of the present invention is to improve such filing devices whereby the documents can be filed with an accessibility hitherto unattainable, and with rapidity and certainty, and the filed documents can be consulted with equal speed, suitable devices being provided for enabling the filing apparatus to be operated with a rapidity hitherto unknown and also to insure great durability notwithstanding an intensive use, and

finally enabling these apparatus to be arranged on or in or built into existing office furniture.

According to this invention a vertical filing drawer is arranged on a specially constructed supporting frame in such a manner as to allow said frame to be built into existing office furniture, while the vertical filing drawer has a mobility and yet a firm support such that the said supporting frame can be drawn out easily and conveniently together with the vertical'filing drawer from the office furniture and moved back into the same. By this means the vertical filing drawer is rendered conveniently accessible while its special construction offers the fur- .ther advantages of convenience, ease in handling and of enabling the documents to be turned over like the leaves of a book.

Several modifications of the present invention are illustrated by way of example in the accompanying drawings, in which:

Figure 1 is a perspective view ci a vertical filing drawer with the improved supporting frame arranged thereon, in the closed position, the letter filing device being omitted for the sake of clearness. Fig. 2 is a perspective viewof the same construction in the completely drawn out position, the letter filing device being similarly omitted for the sake of clearncss. Fig. 3 is a perspective view of part of a desk with the improved apparatus arranged therein and showing also the letter filing device. Fig. 4 shows the same construction fitted in a shelf cabinet. Fig. 5 shows the vertical filing drawer with its special devices arranged in'a filing cabinet. Fig. 6 shows the same arrangement in a pigeonhole box in the position of use, that is to say fitted in a single box of the filing cabinet shown in Fig. 5. Fig. 7 shows the same construction pushed home into the box. F igfS shows a box of this kind with a dust tight fall-down front partly open. Figs. 9, 10, ll, 12 and 13 illustrate modifications of constructions suitable for the arrangements shown in Figs. 1 to 6, provided on the vertical filing drawer for filing the documents.

In carrying the invention into effect as illustrated for the purpose of insuring the ready mobility of the improved filing apparatus and consequently an extremely rapid Working with the latter, the vertical filing drawer g is provided with an actuating device consisting of an under frame r having'two connecting or guiding members I) b formed on their inper sides with grooves c and c. A bar 03 is slidable in these grooves c and o by means of projections 0 and e engaging in the said grooves.

The bar d has a groove-like dove-tail recess f in 'Which'is slidablymounted a slide it of corresponding dove tail shape arranged on the lower part of the vertical filing drawer g. The drawer g has further in its underside a groove like recess '11 fitting the bar (l.v A stop m on the lower bar d limits the movement of the bar d and consequently of the drawer g.

. The drawer g has mounted on it the vertical filing apparatus u,.'u, '0, w, w which may be constructed according to the various modifications shown in Figs. 9, 10, 11, 12 and 13.

The hereinbefore described general arrangement may either be built into an existing article of office furniture as shown for example inFig. 3 in the case of a writing table a and in Fig. 4 in the case of a shelf 12,, or in Fig. 5 in the case of a filing cabinet, or as shown in Figs. 6, 7 and 8 in the case of pigeon hole boxes 0 constituting a filing 12, w and w arranged on the drawer g in its position of use can be drawn out of the article of office furniture (Figs. 3, 4, 5 and 6) owing to its sliding construction and is 7 v vertical position shown in Figs,';3, 4, 5 and then ready for use.

For the purpose of insuring the durability of the filing apparatus, and also the cleanliness of its contents in view of the intensive use of such apparatus in a large and busy office, the container or receptacle shown in Fig. 5 may consist of a filing cabinet composed of pigeon hole boxes 0 shown in Figs. 6 to 8.

Each pigeon hole box 0 has a fall-down front 29 which is pivoted to the box 0 on pins 8 by means of supporting angle bars 1'. On the box 0 are provided stops t which keep the supporting angle bars 1' in such a posisupporting brackets r in order that the clostion that the fall-down front 71) will be kept horizontal when the letter filing drawer is pulled out (Fig. 6). To close the box, it is merely necessary to turn the filing wires u (hereinafter described) of the closing device 1) of the vertical filing drawer (after having placed the covers w and w (Fig. 7) in the vertical position), down into the horizontal position and to .push the vertical filing drawer 9 into the box 0 by means of the front wall as which serves as ahandle. Then the front p is turned up (Fig. 8), recesses 2, Fig. 7, being provided in the limb y of the ing of the front limbs 79 shall not be interfered with by the limbs striking against the stops t. The limbs y which have hitherto been horizontal of the supporting angles 1' will now form a dust-tight closure along the sides 0" of the pigeon hole or of the box 0, while the limbs 11/ of the supporting angle bars 7* constitute at the same time lateral guides for the vertical filing drawer g similar to the actuating device or to the supporting frame a, 6,0, d, e, By this means an extremely durable and securely operating support in the case of'continuous use is provided for the pivoted fall-down front 79 as well as for the sliding vertical filing apparatus, so that the filing apparatus will work properly in spite of intensive use.

- A stop a, Fig. 8, may be providedon the inside of the fall-down front 7) for the purpose of insuring a dust tight closure of the box 0 at the top. Any desired fastening device 0 and a knob 0 may be provided for actuating the dust tight receptacle.

The vertical filing drawer which can be operated with extreme ease and rapidity in combination with p the various articles of office furniture may be employed in various constructions as shown in Figs. 5, 6, 9, 10, 11, 12 and 13.

The frame 4,: shown in Fig. 6 or plate '0 as shown in Fig. 9 has a guiding bar 4) alongwhich two filing wires u can be moved from the center toward the ends and vice also beturned on their guide from their 6 into their horizontal position shown in Fig. 7 for the purpose of engaging the two file covers w, w and holding them in their vertical position, the clips u on the guide bar 4; holding the wires in each position by canting pressure. drawers is provided as shown in Figs. 3, 4, 5, 9, 10, 11, 12, 13 with a transverse removable and fixable slide bar 9 of any suitable cross section which in addition for guiding the covers to and w servesalso as a slide bar for the indicator cards to, file cases, clamping devices or the like.

As shown in Fig. 9, the vertical filing drawer g is further provided with a low front wall as and a frame like back wall '0, which latter carries the holding and closing devices '1), u and u for the'covers w, w.

The wider groove g extending in the middle-of the base plate receives the lockable slide bar 9. On this slide bar between the Each of these vertical inclined covers 11), w provided with guiding eyelets 9 there may be slipped as already.-

the vertical filing drawer to the various constructions and arrangements of office furniture as shown in Figs. 3, 4 and 5 and es-' pecially. for facilitating the building into writing desks and the like. as shown in Fig.

3, the vertical drawer shown in -Figs. 10 and] 11 is constructed in such a manner that one .of the two covers serving. for'holding the contents of the file is pivoted by means of hinges or thelike to the base plate and is guided by means of an arc-shaped sector or the like so that it can be held in its inclined open position, while the other cover w in the same manner as shown in Fig. 9, can automatically adjust itself into the inclined position by means of the limited inclination of the eyelets 9 .01 by angular projections "L02 as well as be held in the closed position by means of a single adjustable holding and closing device.

The drawer g which serves also as a base plate is provided, as shown in Fig..l0, with ofa wire frame or the like, containing the a low front wall m constructed inthe form sliding or guiding bar '11 for a clip u which carries the aforesaid folding filing wire u.

This front wall a: is made low in order that it shall serve only as a ledge like stop for the contents of the file. The higher back wall :12, Figs. 10 and 11, is provided, for example, on its outer side, with a stop pin o Fig. 11, cooperating with the sector bar '0 or similar holding device which holds in its inclined position the cover w that is hinged at o to a side of the base plate g. The arc shaped bar or sector '0 is here fastened to the movable side wall 10 and can be adjusted as desired by means of a nut '22. On unscrewing the nut '0 the cover or side wall 20 of the vertical drawer 9 falls into an inclined open position which is limited by the end of the groove in the sector bar '0 striking the stop -0 Fig. 11.

The second cover w' is slidably held by the transverse slide bar 9' and assumes an inclined position when the filing wire a is loosened, owing to the actionof the angle projections or bent portions 20 that serve as bottom stops.

The holding and closing filing wire {it is cranked to some extent at its lower end to enable it to be raised to the vertical position notwithstanding the low front wall :12.

In the same manner as in using the vertical filing drawers with covers pivoted at one side, for desks, it may be desirable for instance in the case of shelves and the like as shown in Fig. 4, to construct the same apparatus as a duplex vertical filing drawerfor the purpose of enabling the documents filed in a single file to be subdivided, for instance as may be desirable in the case of law suits. By means of this duplex vertical filing drawer documents which are separately filed but belong to one another may be filed away in a single file and when the covers are open the two sets of documents are visible on either side of the file, like the leaves of an open book lying fiat on its back in one and the same vertical file, so that, for example, corresponding, documents or papers setting out opposite views are rendered .visible as has never been done yet in a single file.

Fig. 12 is a front. elevation of the duplex vertical filing drawer in the closed condition, and Fig. 13 is a rear elevation of the duplex vertical filing drawer in its open condition. As shown in these figures, the base plate of this duplex vertical filing drawer g is provided with a frontwall 2: composed, for instance of a strong wire frame or the like which carries the guiding bar n for the folding filing wires u. The higher fixed back wall 01: is provided on its outside with stop pins 1: which cooperate with the arc-shaped sector bars 12 or the like holding devices which hold in an inclined position the outer covers 21: that are hinged at a to the two sides of the base plate. These two pivoting covers 10 which constitute at the same time the sides of the vertical filing drawer areimportant for the practical utilization of these modifications shown in Figs.

12 and 13. The arc-shaped sector bars a are in these cases fixed, for instance, to the outer covers 'w and can be adjusted as desired by means of set nuts a In Fig. 12 the outer covers w are shown screwed fast in the vertical position. On loosening the nuts '0 they fall into the inclined open position, Fig. 13, after the vertical filing drawer has been pulled out of the container (for instance the shelf cabinet shown in Fig. 4) until the ends 12 of the sector bars a strike the stop pins 12 The two inner covers w corresponding to the two outer covers 10 are slidably arranged on the transverse slide bar 9 and they assume the inclined position after the filing wires ,u'have been loosened, owing to the action of the angular stops or bent portions 20 that serve as bottom stops. The fil ing wires u are also somewhat cranked at their lower ends as in the construction shown in Fig. 10, in order that they may be able to assume an upright position notwithstanding the low front wall frame w. Each of the two files thus formed in a single vertical filing drawer can in this arrangement as shown in Fig. 12 be brought into the visible open position shownin Fig. 13 which not only allows of readily reading, turning over the leaves and filing the documents but also facilitates a comparison of the contents of the one file with the contents of the other thereon, provides a vertical filing cabinet which is able to satisfy the highest requirements of a great business as regards oer-- tainty. durability, rapidity of filing. accessibility and visibility in use. finding the documents. and cleanliness and neatness in storing same. This constitutes a device, the high practical value of which will be particularly appreciated where a large number of documents have to be. filed daily and consulted again quickly without having to damage the documents by perforations or the like.
